description
The CD54HCT4017 is a high-speed silicon-gate CMOS 5-stage Johnson counter with ten decoded outputs.
Each decoded output normally is low and sequentially goes high on the low-to-high transition of the clock (CP)
input. Each output stays high for one clock period of the ten-clock-period cycle. The terminal count (TC) output
transitions low to high after output ten (9) goes low, and can be used in conjunction with the clock enable (CE)
input to cascade several stages. CE disables counting when in the high state. The master reset (MR) input, when
taken high, sets all the decoded outputs, except 0, to low.
The CD54HCT4017 is characterized for operation over the full military temperature range of –55°C to 125°C.

NOTES: A. CL includes probe and test-fixture capacitance.
B. Waveform 1 is for an output with internal conditions such that the output is low except when disabled by the output control.
Waveform 2 is for an output with internal conditions such that the output is high except when disabled by the output control.
C. Phase relationships between waveforms were chosen arbitrarily. All input pulses are supplied by generators having the following
characteristics: PRR ≤ 1 MHz, ZO = 50 Ω, tr = 6 ns, tf = 6 ns.
D. The outputs are measured one at a time with one input transition per measurement.
E. tPLZ and tPHZ are the same as tdis.
F. tPZL and tPZH are the same as ten.
G. tPLH and tPHL are the same as tpd.
